Remote controls do not send the same ir signal every time you press the same button.

On the wiki page you referenced there is a section regarding the key codes to be placed in the remote configuration device data - there can be multiple codes for each key.

I am aware of this. I actually put that information on that wiki page myself some time ago. With a well functioning USB-UIRT/remote setup, I usually see exactly two different codes for each button.

The problem I am describing is not the two distinct codes from the remote. Rather, the problem is that for the same button, the two codes that are received on each of MD#1 and MD#2 do not match. That is, if you learn the codes on MD#1, they are different from those learned on MD#2.
